The Jaguars' offense took another hit Wednesday, when wide receiver Laurent Robinson went on injured reserved because of a concussion.

Gabbert injured his right shoulder and forearm in Sunday's game against the Houston Texans. He was replaced by Chad Henne, who played extremely well in defeat. Henne put up four touchdown passes, 354 passing yards and a 126.8 passer rating, but the Jaguars lost in overtime.

Gabbert, 23, had been playing with a left shoulder injury from a few weeks ago. In two seasons with the Jaguars, Gabbert has 21 touchdown passes and 17 interceptions, and his tenure has been a disappointment for both him and the team. The Jaguars are 1-9 this season, and Gabbert has a career starting record of 5-19 and a career passer rating of 70.2.

The Jaguars traded up to take Gabbert with the 10th overall pick in 2011, and he took over as the starter in Week 3 last season.

If Henne plays well the remainder of the season, it will raise even more questions about Gabbert's future with the Jaguars.
